Vibriolysin, a new agent for enzymatic debridement, was recently shown to rapidly and thoroughly hydrolyze burn wound eschar within full-thickness wounds. The safety of this agent and its subsequent effect on wound healing processes have yet to be established and are addressed in this study. Within the context of a porcine partial-thickness burn wound model, the enzyme was shown to digest desiccated eschar after two applications, whereas four applications of another enzymatic preparation were required. ⋯ The data indicate that wounds treated with Vibriolysin exhibited significant dose-responsive stimulation of granulation tissue (neodermis) as compared with control treatment groups. Repeated protease applications did not convert partial-thickness burns to full-thickness wounds, and no adverse inflammatory responses were detected between 1 and 10 days. The results suggest that in addition to its documented efficacy in the debridement of burn eschar, Vibriolysin may have beneficial effects on dermal reparative events.
